RETRACTED: Comparative effectiveness of low‐level laser therapy and transcutaneous electrical nerve stimulation in symptomatic Temporomandibular Disorders: A Randomised Control Trial

Abstract

BackgroundMyofascial pain is one of the most common facial region pains, presenting itself with various signs and symptoms like tenderness of masticatory muscles and difficulty in mouth opening. Considering its multifactorial aetiology various treatment modalities are present.ObjectiveThe aim of this study is to compare the effectiveness of transcutaneous electrical nerve stimulation (TENS)and low‐level laser therapy (LLLT) for the patients of temporomandibular disorders (TMDS).MethodsThe study was conducted with 20 patients diagnosed with TMDS. Group A received LLLT at 660 nm, 6 J/point, two sessions/week for 4 weeks and group B received TENS at 2–250 Hz, two sessions/week for 4 weeks.ResultsPain Score decreased and mouth opening increased in both groups with time, however, the difference between the two groups was not statistically significant. Right and left lateral excursions showed improvement at different intervals in both groups. However, the LLLT group showed significant improvement.ConclusionClinical trial showed improvement in visual analogue scale (VAS), maximum mouth opening (MMO) and lateral excursion in the different time intervals in both the groups with LLLT showed more improvement with lateral excursions movements.

Effect of Photobiomodulation Therapy Dosage on Orthodontic Movement, Temporomandibular Dysfunction and Third Molar Surgery Outcomes: A Five-Year Systematic Review

“…It is evident that a wide variety of laser irradiation protocols have been performed. Regarding the wavelength applied, the vast majority was in the near-infrared range (780-940 nm), while five studies [61,67,70,76,77] examined the red wavelengths, and two [59,60], the 1064 nm wavelength.…”

“…As for the treatment outcomes observed, 12/20 studies (60%) [59][60][61][62][63][64]66,67,70,[73][74][75]] presented a positive result, while 8/20 (40%) [65,68,69,71,72,[76][77][78] showed no difference from the control group.…”
